Selection Table
The devices include a comprehensive range of features, with most features common to all devices. The main features
distinguishing them are Voice ROM capacity and power supply voltage. The functional differences between the de-
vices are shown in the following table. Devices which include an
²A² in their part number are Mask type while devices
which contain an
²R² in their part number are OTP type.
